Checking and refilling levels
WARNING (Continued)
● Once the engine has cooled, follow the instructions below before
opening the bonnet:
–Turn on the electronic parking brake and place the gear selector
lever in P or the gearbox lever in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them unsupervised.
● When the engine is warm or hot, the cooling system is pressurised.
Do not unscrew the cap on the expansion tank when the engine is hot.
Otherwise, coolant may spray out under pressure causing burns and seri-
ous injury.
–Carefully and slowly unscrew the cap anticlockwise, gently press-
ing down on it.
– Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire.
WARNING
The high voltages of the electrical system can give electric shocks as well
as causing burns and serious injury and possibly even death!
● Never cause short circuits in the electrical system. The battery could
explode.
● To minimise the risk of electric shock and serious consequences
while the engine is running or starting the engine, note the following:
–Never touch the electrical wiring of the ignition system.
– Never touch electric cables or the gas discharge lamps.
WARNING
In the engine compartment, there are rotating parts that could cause se-
rious injury.
● Never place your hands on or near the radiator fan. Touching the rotor
blades could seriously harm you. The ventilator works according to the
engine temperature and could start suddenly even when the ignition is
turned off and the key is removed.
● If any work has to be performed when the engine is started or with
the engine running, there is an additional, potentially fatal, safety risk
from the rotating parts, such as the drive belts, alternator, radiator fan
etc as well as from the high-voltage ignition system. Always work with
the utmost caution.
–Always make sure that no parts of your body, jewellery, ties, loose
clothing and long hair can be trapped by the rotating parts of the en-
gine. Before any work, remove ties and jewellery ( necklaces, etc), tie
longhair back and tie all items of loose clothing to your body to make
sure that they cannot be trapped by engine components.
– Take extreme caution when operating the accelerator and remain
attentive. The vehicle could move, even with the electronic parking
brake activated.
● Always make sure you have not left any objects, such as cloths or
tools, in the engine compartment. If any object is left in the engine com-
partment, this could cause malfunctions, engine faults and even a fire.
WARNING
Refill liquids and certain materials can catch fire easily in the engine
compartment, causing a fire and serious injury!
● Never smoke.
● Never work close to places exposed to flames or sparks.

Engine oil Introduction
Additional information and warnings:
● ⇒ Booklet Maintenance Programme
● Working in the engine compartment ⇒ page 278
● Accessories, parts replacement, repairs and modifications ⇒ page 260
WARNING
Incorrectly handling engine oil can cause injury and serious burns.
● Always protect your eyes when handling engine oil.
● Oil is toxic and must be kept out of the reach of children.
● Engine oil must only be kept closed in its original container. The same
applies to use oil until it has been disposed of.
● Never store engine oil in empty food containers or bottles as other
people may accidentally drink it.
● Regular contact with engine oil can be bad for the skin. If you come
into contact with engine oil, wash your skin with soap and water.
● With the engine running, the engine oil gets extremely hot and can
cause severe skin burns. Always wait until the engine has fully cooled.
For the sake of the environment
Similar to the other service liquids, spilled engine oil can be bad for the en-
vironment. Collect any spilt fluids in suitable containers and dispose of in
accordance with legislation and with the utmost respect for the environ-
ment.

compartment: Engine oil
filler cap Preparations
●
Park the vehicle on flat ground so that the engine oil reading is correct.
● Stop the engine and wait a few minutes for the oil to drain back into the
sump. When the engine has cooled down, immediately check the oil level
and top up if necessary.
● Open the bonnet ⇒ page 278.
● The engine oil filler neck can be recognised by the symbol on the
cap ⇒ Fig. 171 and the dipstick by its coloured handle.
Checking the engine oil level
● Pull out the dipstick and wipe it on a clean cloth.
● Replace the dipstick, pushing it in as far as it will go. If the dipstick has a
mark, when you reintroduce it this mark should slot into the corresponding
groove located on the upper end of the tube.
● Remove the dipstick again and check the engine oil level ⇒ table on
page 284.
● After reading the oil level, replace the dipstick in the tube completely.
Engine oil topping up ranges
Fig. 170Operations required depending on the engine oil topping
up level:
Area ADo not top up oil
⇒ .
Area BAdd approximately 0.5 L of oil (1/2 quarter of a gallon).
The oil level can be in the zone A, but never above A.
Area CIt is
essential to add oil (approximately 1 litre or quarter of
a gallon). Ensure that the level is around the centre of the
zone B
after adding oil.
Adding oil after checking the level
Only add engine oil in small quantities and in steps.

compartment: Coolant
expansion tank cap
If the coolant level is low, the coolant warning indicator will light. Preparations
●
Park the vehicle on even, flat and firm ground.
● Allow the engine to cool ⇒
.
● Open the bonnet ⇒ page 278.
● The coolant expansion tank is easily recognisable because of the sym-
bol on the cap ⇒ Fig. 174.
Checking the engine coolant level
● When the engine is cold, check the coolant level using the side marking
on the expansion tank ⇒ Fig. 173.
● If the level is below the “MIN” mark, top up with coolant. When the en-
gine is hot it may be slightly above the marked area.
Topping up the engine coolant level
● Always protect your face, hands and arms from hot coolant and steam
using a large, thick cloth over the coolant expansion tank cap.
● Remove the cap very carefully ⇒
.
● Only refill using new engine coolant according to SEAT specifications
(⇒ page 288) ⇒
.
● The engine coolant level should be between the marks on the coolant
expansion tank ⇒ Fig. 173. Do not exceed the top level of the marked area
⇒
.
● Screw on the cap tightly.
● If, the event of an emergency, you have no coolant that is compliant to
the required specifications ( ⇒ page 288), never use another type of addi-
tive. Instead, first top up with distilled water ⇒
only. Then re-establish
the correct proportion of the mixture with the correct additive as soon as
possible ⇒ page 288.

WARNING
Hot vapours and coolant can cause serious burns.
● Never open the coolant expansion tank if steam or coolant is coming
from the engine compartment. Wait until you cannot see or hear any
steam or coolant escaping.
● Always wait until the engine has completely cooled before very care-
fully opening the expansion tank cap. Contact with hot elements of the
engine can cause skin burns.
● Once the engine has cooled, follow the instructions below before
opening the bonnet:
–Turn on the electronic parking brake and place the gear selector
lever in P or the gearbox lever in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them unsupervised.
● When the engine is warm or hot, the cooling system is pressurised.
Do not unscrew the cap on the expansion tank when the engine is hot.
Otherwise, coolant may spray out under pressure causing burns and seri-
ous injury.
–Carefully and slowly unscrew the cap anticlockwise, gently press-
ing down on it.
– Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire. Under specific cir-
cumstances, the ethylene glycol can catch fire.CAUTION
● Top up with distilled water only. Any other type of water may lead to con-
siderable rusting in the engine due to its chemical components. This could
consequently damage the engine. If you have not used distilled water but
another type of water to top up the coolant, a specialised workshop must
immediately replace all of the fluid in the engine cooling system.
● Only top up coolant to the top level of the marked area ⇒ Fig. 173. Oth-
erwise the excess coolant will be forced out of the cooling system when the
engine is hot, causing damage.
● If a lot of liquid coolant has been lost, wait for the engine to cool down
completely before adding coolant. Extensive coolant loss is an indication of
leaks in the engine cooling system. Have the engine cooling system inspec-
ted immediately by a specialised workshop. Otherwise you may damage the
engine.
● When refilling or changing service liquids, ensure that you put the liq-
uids into the right tank. Making a mistake when refilling could cause seri-
ous malfunctions and damage the engine!
